ampano noun "building" (especially of wood), "wooden hall" (PAN; alternative form umpano, VT45:36, which Tolkien in one case altered to ampano, VT46:8). In the pre-classical Tengwar system presupposed in the Etymologies, ampano was also the name of tengwa #6 (VT46:8), which letter Tolkien would later call umbar instead (changing its value from mp to mb).
